Compiler Warning (level 4) C4130

'operator' : logical operation on address of string constant

Using the operator with the address of a string literal produces unexpected code.

Example

char *pc;
pc = "Hello";
if (pc == "Hello")
   { }

The if statement compares the value stored in the pointer pc to the address of the string "Hello", which is allocated separately each time the string occurs in code. The if statement does not compare the string pointed to by pc with the string "Hello".

To compare strings, use the strcmp function.
